Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail.
Such as Fig. 1, shown in Fig. 2, pipeline demister, including: except water smoke chamber 1, before and after except water smoke chamber 1, both sides are respectively arranged with gas feed 11 and gas outlet 12, it is also respectively provided with adpting flange in the outer end of gas feed 11 and gas outlet 12, pipeline demister of the present invention needs to be serially connected with on gas transmission pipeline in use, adpting flange in gas feed 11 and gas outlet 12 is to arrange to fix with the Flange joint on conveyance conduit, can discharge except the sewage draining exit 13 of water in water smoke chamber 1 except the bottom 14 of water smoke chamber 1 is additionally provided with, in the present embodiment, except the bottom 14 of water smoke chamber 1 is bottom funnel-shaped portion, the outlet of bottom funnel-shaped portion is sewage draining exit 13, bottom funnel-shaped portion can preferably collect water；Between gas feed 11 and gas outlet 12 except water smoke chamber 1 in be provided with baffling grid 2, in the present embodiment, baffling grid 2 is arranged at the top of sewage draining exit 13, the position of baffling grid 2 so arranges and the layout of pipeline demister can be made more reasonable, enter except the gas of water smoke chamber 1 flows to gas outlet 12 after baffling grid 2 from gas feed 11, arranging, between bottom and the bottom 14 removing water smoke chamber 1 of baffling grid 2, first time liquid passage 21 that water can be allowed to flow through, baffling grid 2 is formed by some pieces of upright deflection plate 22 spacing side by side arrangements；Silk screen layer 3 before being provided with between baffling grid 2 and gas feed 11 in except water smoke chamber 1, the bottom of front silk screen layer 3 is less than gas feed 11 and higher than except the diapire of water smoke chamber 1, the bottom of front silk screen layer 3 and enter the first gas passage 31 of baffling grid 2 below gas silk screen layer 3 in the past except the gap formed between the diapire of water smoke chamber 1 constitutes to allow, when front silk screen layer 3 is plugged, gas can be walked around front silk screen layer 3 by the first gas passage 31 and enter in baffling grid 2, additionally, water in gas can caught during gas collisions by the front silk screen layer 3 blocked；Silk screen layer 4 after being provided with between baffling grid 2 and gas outlet 12 in except water smoke chamber 1, it is provided with, between bottom and the bottom 14 removing water smoke chamber 1 of rear silk screen layer 4, second time liquid passage 42 that water can be allowed to flow through, the top of rear silk screen layer 4 is higher than gas outlet 12 and less than except the roof of water smoke chamber 1, the gap formed between top and the roof removing water smoke chamber 1 of rear silk screen layer 4 constitutes the second gas passage 41 that gas can be allowed to pass through above rear silk screen layer 4, when rear silk screen layer 4 is plugged, gas can be by the second gas passage 41 in silk screen layer 4 enters gas outlet 12 later, additionally, water in gas can caught during gas collisions by the rear silk screen layer 4 blocked；The gas passage on the bottom of front silk screen layer 3 and the top of rear silk screen layer 4 is arranged, it is ensured that even if silk screen layer resistance increases the throughput affecting air-flow after long-play, still ensures that the lower resistance of equipment, thus reaches not affect the purpose of the stable operation of system.In the present embodiment, the top of baffling grid 2 leans with except the top of water smoke chamber 1, and the left and right sides of baffling grid 2 leans with except the left and right sides of water smoke chamber 1 respectively；The top of front silk screen layer 3 leans with except the top of water smoke chamber 1, and the left and right sides of front silk screen layer 3 leans with except the left and right sides of water smoke chamber 1 respectively；The left and right sides of rear silk screen layer 4 leans with except the left and right sides of water smoke chamber 1 respectively, so arrange can prevent the most premenstrual silk screen layer of gas 3, baffling grid 2, rear silk screen layer 4 except water smoke directly through pipeline demister.Flowing into from gas feed 11 carries out for the first time except water smoke except the gas of water smoke chamber 1 first passes through front silk screen layer 3, water in gas can be caught by the mesh in front silk screen layer 3, the water caught can fall to the bottom 14 except water smoke chamber 1 on the past silk screen layer 3, and then water flows in sewage draining exit 13 through first time liquid passage 21 and discharges；Next gas carries out second time except water smoke through baffling grid 2, when gas is through baffling gap 221 two adjacent baffle 22 in baffling grid 2, baffling gap 221 can make gas flow generation deviation, the water in gas is made to collide with deflection plate 22 and be captured, the water caught can flow downward in first time liquid passage 21 along deflection plate 22, discharges during then water flows into sewage draining exit 13；Next gas is carried out for the third time except water smoke through rear silk screen layer 4, and the water in gas can be caught by the mesh in rear silk screen layer 4, and the water caught can fall in second time liquid passage 42 from rear silk screen layer 4, discharges during then water flows into sewage draining exit 13；Eventually pass three times and remove water smoke chamber 1 except the gas of water smoke flows out from gas outlet 12.
In the present embodiment, it is being also respectively provided with the first flush pipe 16 front silk screen layer 3 being rinsed and the second flush pipe 17 rear silk screen layer 4 being rinsed except the top of water smoke chamber 1, so arrange and front silk screen layer 3 and rear silk screen layer 4 can be made to be difficult to by the dust in gas block, and except the top of water smoke chamber 1 is arranged to removable cover 15, so arranges and the inside to pipeline demister can be facilitated to safeguard.Spacing between front silk screen layer 3 and baffling grid 2 is not less than 10cm, and the spacing between rear silk screen layer 4 and baffling grid 2 is not less than 10cm, front silk screen layer 3 and rear silk screen layer 4 arrange with baffling grid 2 cross near easily increase gas by time resistance.Front silk screen layer 3 is the high-penetrability silk screen layer that penetration performance is excellent, rear silk screen layer 4 is except the excellent high efficiency silk screen layer of water smoke performance, gas without except during water smoke the water content of gas the highest, so gas easily forms liquid film when through front silk screen layer 3 on front silk screen layer 3, thus block front silk screen layer 3, in order to reduce the probability that front silk screen layer 3 is plugged, so front silk screen layer 3 is set to the high-penetrability silk screen layer that penetration performance is excellent, the mesh density on high-penetrability silk screen layer is relatively dredged and mesh aperture is bigger；Gas is after premenstrual silk screen layer 3 and baffling grid 2 remove water smoke, the water content step-down of gas, thus be difficult on rear silk screen layer 4 produce liquid film, therefore being set to rear silk screen layer 4 except the high efficiency silk screen layer that water smoke performance is excellent reduces the water content of gas further, the mesh density on high efficiency silk screen layer is closeer and mesh aperture is less.
The invention have the benefit that pipeline demister of the present invention can carry out three times except water smoke in the case of ensureing less equipment resistance to gas so that the water content of gas is substantially reduced, thus substantially increases the service life of gas transmission pipeline.
